Paul Samuelson made a series of important contributions to population theory for humans and other species, evolutionary theory, and the theory of age structured life cycles in economic equilibrium and growth. The work is highly abstract but much of it was intended to illuminate issues of...

This paper documents the effect of primary forest cover loss on increased incidence of malaria. The evidence is consistent with an ecological response. I show that land use change, anti-malarial programs or migration cannot explain the effect of primary forest cover loss on increased malarial...

We study the consequences of a working time reduction (WTR hereafter) in an exogenous growth model with unemployment (due to efficiency wage considerations) and a renewable natural resource. The resource is an essential input whose marginal productivity is bounded by physical laws. In the...

This paper studies the interplay between left-handedness and economic development. To explain the decline and subsequent recovery of left-handedness observed over the last few centuries in the Western world, we propose a theory in which economic development influences the prevalence of...

Soil tests provide information that can help farmers to reduce costs, increase yields and profits, and contribute to sustainable soil health, yet they are rarely used. In this study, we elicit small-scale farmers' willingness-to-pay (WTP) for rapid, low-cost soil tests using incentive-compatible...

We use the adaptive cycle theory to improve our understanding of cycles of urban change in the city of Barcelona from 1953 to present. Most specifically, we explore the vulnerabilities and windows of opportunity these cycles for change introduced in the release (Ω) and reorganization (α)...

We study how air pollution impacts the U.S. labor market by analyzing effects of drifting wildfire smoke that can affect populations far from the fires themselves. We link satellite smoke plume with labor market outcomes to estimate that an additional day of smoke exposure reduces quarterly...

This study is one of the first investigating the causal evidence of the morbidity costs of fine particulates (PM2.5) for all age cohorts in a developing country, using individual-level health spending data from a basic medical insurance program in Wuhan, China. Our instrumental variable (IV)...

What do markets for voluntary climate protection imply about people's valuations of en- vironmental protection? I study this question in a large-scale field experiment (N=255,000) with a delivery service, where customers are offered carbon offsets that compensate for emissions. To estimate...

Recent research suggests that short-term exposure to air pollution is associated with an elevated prevalence of respiratory infectious disease. We examine the relationship between the air quality index (AQI) and weekly cases of influenza-like illnesses (ILI) and COVID-19 in the United States. We...
